The Scarlet-horned Manakin is a passeriforme of the family Pipridae.
It is 12.5 cm in length. The male is black with a red head on which the feathers of the hindcrown are elongated to form two “horns”. The thighs are also red and the iris is white. The female is olive-green with a paler belly. There is a slight tuft on the hindcrown and the iris is darker than the male's.
Like other members of the family, the male has a complex lekking display. The red thighs are displayed conspicuously and there are rapid flights, tail flicking and “moon-walking” involved. The lek size is smaller than in many congeners.
It is uncommon to locally fairly common in humid forest and mature secondary woodland on tepuis at between 500 and 1800 metres.
As a bird of the tepuis it is present in Brazil only in the state of Roraima in the upper Rio Branco and, as Robson Czaban's photo shows, on the Pico da Neblina in the upper Rio Negro. It is found in adjacent areas of Venezuela and Guyana.
